Description

TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of powder conveying equipment, and specifically relates to a hopper for powder conveying. BACKGROUND

[0002] In the industrial production field, powder conveying is a very common and key link, and is widely used in many industries such as chemical industry, food, pharmaceutical, building materials and the like. In the powder conveying process, the hopper is an important equipment for storing and transferring powder, and its performance and operating condition directly affect the stability and efficiency of the whole conveying system. Among many hopper structures, the conical hopper is widely used because it can utilize gravity to make powder naturally converge to the bottom end and facilitate concentrated discharge. However, in the actual application process, when a large amount of powder is concentrated to discharge and convey outward through the conical hopper, some problems are prone to occur.

[0003] On the one hand, due to the differences in the characteristics of the powder itself, such as particle size, shape, humidity and fluidity, the friction and interaction between different powders will cause the flow state of the powder to become complex when passing through the conical hopper. When a large amount of powder flows into the conical hopper at the same time, this complex flow state is easy to cause excessive accumulation of powder in some parts of the conical hopper. On the other hand, with the continuous expansion of the industrial production scale, the conveying amount of powder is also increasing. In this case, the discharge speed and capacity of the conical hopper are facing greater challenges. A large amount of powder quickly enters the conical hopper, while the discharge port of the conical hopper is relatively limited and cannot timely and smoothly discharge all the powder, which further aggravates the accumulation of powder in the hopper. Once the powder is blocked in the conical hopper, not only the normal conveying of the powder is interrupted, but also the continuity of production is affected, and the production efficiency is greatly reduced, and the production cost is increased.

[0004] In summary, the existing powder conveying hopper has obvious deficiencies in dealing with the concentrated discharge and conveying of a large amount of powder, and there is an urgent need for an innovative technical solution that can effectively solve the problems of excessive accumulation and blockage of powder to improve the stability, reliability and production efficiency of powder conveying.

[0022] This utility model provides, for example Figures 1-4 The diagram shows a hopper for powder conveying, comprising a conical hopper 5 and a cylindrical hopper 6 positioned at the top of the conical hopper 5. The conical hopper 5 and the cylindrical hopper 6 are internally connected. The cylindrical hopper 6 provides a larger powder storage space, while the conical hopper 5 utilizes its special conical structure to allow the powder to naturally converge towards the bottom under gravity, facilitating concentrated discharge. This structural design conforms to the gravity flow characteristics of powder, effectively utilizing gravity as the power source for powder conveying. Furthermore, the inner walls of both the conical hopper 5 and the cylindrical hopper 6 are smooth and burr-free. The smooth, burr-free inner walls minimize the friction between the powder and the hopper's inner wall, reducing friction and contributing to... The powder flows freely within the hopper, preventing it from adhering to the inner wall and accumulating due to friction. This ensures the continuity and stability of powder conveying. The top of the cylindrical hopper 6 is equipped with an end cap 7. The main function of the end cap 7 is to seal the top of the hopper, preventing external impurities from entering the hopper and contaminating the powder. It also provides a certain degree of sealing to the inside of the hopper, helping to maintain a relatively stable environment. The center of the end cap 7 is equipped with a feeding port 8. The central design of the feeding port 8 ensures that the added powder is evenly dispersed within the cylindrical hopper 6, preventing uneven distribution of powder within the hopper due to eccentric feeding position, which would affect the subsequent conveying process.

[0023] like Figure 1 and Figure 2As shown, the top end of the conical hopper 5 is equidistantly welded with multiple placing pillars 3, the multiple placing pillars 3 are all arranged in a downward vertical state, the multiple placing pillars 3 are all connected with a pillar connecting rod 2 between the lower sides of the centers of the multiple placing pillars 3, the bottom end of the multiple placing pillars 3 is all provided with a moving wheel 1, and the moving wheel 1 is a universal wheel, the design of the universal wheel gives the hopper good moving flexibility, which can conveniently move the hopper to different positions for feeding, discharging or equipment maintenance and other operations, greatly improving the use convenience of the hopper and the operability of the equipment, and the bottom end of the conical hopper 5 is also provided with a flange outside the opening, the flange is fixed with a discharge valve 4 at the bottom end through multiple screws, the discharge valve 4 is in communication with the inside of the conical hopper 5, the discharge valve 4 is a key component for controlling the discharge of the powder, and the discharge valve 4 can accurately control the discharge amount and speed of the powder, and flexibly adjust according to the actual production requirements, so as to realize effective control of the powder conveying process, when the powder needs to be conveyed, first add the powder into the hopper through the feeding port 8 at the center of the end cover 7, the powder is stored in the cylindrical hopper 6 under the action of gravity, and then gradually falls into the conical hopper 5, due to the special shape of the conical hopper 5, the powder converges to the bottom end under the action of gravity, and finally is discharged through the bottom end opening of the conical hopper 5 through the discharge valve 4, the discharge valve 4 controls the discharge flow and speed of the powder according to the actual requirements, and realizes stable powder conveying.

[0024] As Figure 1 , Figure 3 and Figure 4The lifting type dredging device 9 is arranged on the right side of the feeding opening 8. This arrangement does not affect the normal feeding from the feeding opening 8, and can timely play a dredging role in the key area where the powder is prone to blockage. The lifting type dredging device 9 includes a triangular dredging block 10, a dredging vertical rod 11, a horizontal connecting rod 12, a vertical connecting rod 13 and a lifting guide sleeve 14. A square hole is arranged inside the right side of the center of the end cover 7. The square hole is provided with the lifting guide sleeve 14 at the top end. The lifting guide sleeve 14 is fixed on the outer wall of the top end of the end cover 7 by welding. The square hole and the lifting guide sleeve 14 at the top end provide a track for the vertical movement of the vertical connecting rod 13. The lifting guide sleeve 14 is fixed on the outer wall of the top end of the end cover 7 by welding, which ensures the stability of the structure and provides reliable support for the vertical connecting rod 13 during movement. The lifting guide sleeve 14 is inserted with the vertical connecting rod 13 in the square hole. The vertical connecting rod 13 is located inside the top end of the end cover 7 and the inside of the cylindrical hopper 6 at the upper and lower ends respectively. The dredging vertical rod 11 is connected to the left end of the vertical connecting rod 13. The dredging vertical rod 11 is provided with a plurality of triangular dredging blocks 10 around the outer wall.

It enables the vertical connecting rod 13 to move up and down with other components as needed to deal with different positions of the powder blockage. The center point of the dredging vertical rod 11 is vertically coincided with the center point of the conical hopper 5. The vertical coincidence of the center points ensures that the dredging vertical rod 11 can accurately insert into the central area of the conical hopper 5 where the powder is prone to accumulate and blockage when it is lowered, improving the dredging efficiency. The bottom end of the dredging vertical rod 11 is designed as a cone, and the direction of the cone tip at the bottom end is downward. The cone design facilitates easier insertion into the caked or blocked powder during the lowering process, reduces the insertion resistance, and can effectively break the powder caking. The cross-sectional shape of the dredging vertical rod 11, the horizontal connecting rod 12 and the vertical connecting rod 13 is a square.

The triangular tips of the triangular dredging blocks 10 point downward, and the top end outer wall of the triangular dredging blocks 10 is in a flat state. During the upward movement of the dredging vertical rod 11, the flat outer wall can effectively drive the powder above it upward, preventing the powder from falling back and accumulating during the upward movement. During the downward movement, the triangular tips can further break up the powder lumps, enhancing the dredging effect. The lifting dredging device 9 also includes a return spring 15 and a horizontal top frame 16. The top end of the vertical connecting rod 13 is welded with the horizontal top frame 16, and the return spring 15 is arranged between the horizontal top frame 16 and the lifting guide sleeve 14, and the return spring 15 is sleeved outside the vertical connecting rod 13. When the vertical connecting rod 13 is pulled up by the vertical pull rod 17 and then the vertical pull rod 17 is released, the return spring 15 can generate a downward elastic force to quickly reset the horizontal top frame 16 and the vertical connecting rod 13, so that the dredging vertical rod 11 returns to the initial position, ready for the next dredging operation, achieving the automatic reset function, improving the convenience and continuity of operation. The horizontal top frame 16 provides a support point for the return spring 15 and serves as a connecting component of the vertical pull rod 17, making it easy for the operator to pull the vertical pull rod 17 to drive the vertical connecting rod 13 to rise, which is an important connecting and force-bearing component of the entire lifting mechanism.

[0026] As Figure 1 , Figure 3 and Figure 4As shown, the lifting type dredging device 9 further comprises a vertical pull rod 17 and a pull ring 18, the vertical pull rod 17 is arranged at the bottom of the right end of the horizontal top frame 16, and the vertical pull rod 17 is located at the right side of the outer wall of the right end of the cylindrical hopper 6, the pull ring 18 is arranged at the bottom end of the vertical pull rod 17, the design of the vertical pull rod 17 and the pull ring 18 arranges the operating part at a position outside the hopper which is obvious and easy to operate, the operator does not need to enter the inside of the hopper, and the upward movement of the vertical connecting rod 13 can be easily controlled by pulling the pull ring 18, thereby realizing the lifting control of the dredging vertical inserting rod 11, greatly improving the convenience and safety of operation, and when it is observed that the powder conveying process is blocked, the operator pulls the pull ring 18 at the bottom end of the vertical pull rod 17, the pull ring 18 drives the vertical pull rod 17 to move upward, the vertical pull rod 17 further pulls the horizontal top frame 16 and the vertical connecting rod 13 to move upward in the lifting guide sleeve 14 and the square hole, along with the upward movement of the vertical connecting rod 13, the dredging vertical inserting rod 11 connected thereto also moves upward synchronously, in the upward movement process, since the top end outer wall of the triangular dredging block 10 is in a planar state, the powder above the triangular dredging block 10 is driven upward, effectively avoiding the re-accumulation of the powder in the upward movement process, when the pull ring 18 is released, the horizontal top frame 16 is subjected to downward elastic force under the action of the reset spring 15, drives the vertical connecting rod 13 and the dredging vertical inserting rod 11 to move downward quickly, at this time, the cone at the bottom end of the dredging vertical inserting rod 11 is inserted into the powder blockage that may exist first, the staggered triangular dredging blocks 10 break and disperse the caked or blocked powder, so as to repeatedly pull and release the pull ring 18, the dredging vertical inserting rod 11 continuously moves upward and downward, through the driving, breaking and dispersing actions of the triangular dredging blocks 10, the powder in the hopper is continuously dredged, so as to ensure that the powder can be smoothly conveyed through the conical hopper 5 and the discharge valve 4, and maintain the normal operation of the powder conveying system.
